We look at the division of 183631 by 93 
The aim is to understand the frequency of 93 in 183631.

On to step 1:
93 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 93

Let's proceed to step 2:
The number 93 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 93

Step 3:
If we divide 183 by 93, we get 1 and a remainder of 90.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 93 from 183 and we're left with 90.
Take the next digit (6) from the dividend and append it to 90, then repeat: 906 / 93

Step 4:
93 goes into 906 9 times with a remainder of 69.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 837 from 906 and we're left with 69.
Include the next digit (3) from the dividend after 69, then repeat: 693 / 93

Moving on to step 5:
693 divided by 93 is 7 with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 197.0
Deduct 651 from 693 and we're left with 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 93

Going ahead to step 6:
421 divided by 93 is 4 with a remainder of 49.
Use 4 as the next digit of our solution. 
Result so far: 1974.0
The remainder is 49 after subtracting 372 from 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
The number 93 fits into 490 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 1974.5
If we subtract 465 from 490, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
If we divide 250 by 93, we get 2 and a remainder of 64.
The next digit of our result is 2. 
Result so far: 1974.52
If we take 186 away from 250, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
93 goes into 640 6 times with a remainder of 82.
Write down 6 as next digit of the result. 
Result so far: 1974.526
The remainder is 82 after subtracting 558 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 10:
93 goes into 820 8 times with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 1974.5268
The remainder is 76 after subtracting 744 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 11:
If we divide 760 by 93, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 1974.52688
Subtracting 744 from 760 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 1974.52688 and a remainder of 1.6e-05.
